Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW9009 (1990)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9009 conducted in 1990 (Chief Scientist: Dr. Gregory Mountain). These data files are of MGD77 format and include Singlebeam Bathymetry data and were processed after data collection. Data were acquired as part of the project(s): Geometry and Timing of Upper Oligocene to Miocene Depositional Sequences on the U.S. Middle Atlantic Margin, and funding was provided by NSF grant(s): DPP89-11810, OCE92-03282, and OCE92-03344.

本数据集系采用搭载于船舶上的Atlas Hydrosweep DS多波束声纳系统于1990年进行的Maurice Ewing探险EW9009（首席科学家：格雷戈里·芒山博士）期间获取。数据文件格式为MGD77，包含单波束测深数据，并在数据采集后进行处理。数据采集作为项目的一部分：美国中大西洋边缘上新 oligocene至Miocene沉积序列的几何形态与时间序列，并由NSF（美国国家科学基金会）资助，资助编号分别为DPP89-11810、OCE92-03282及OCE92-03344。
